To all whom it may concern:

Be it known that I, CLYDE O. CONNOR, a citizen of the United States, anda resident of Wichita, in the county of Sedgwiek and State of Kansas,have. invented certain new and useful Improvements in Hair-ClipperBlades, of which the following is a description, referring to thedrawings which accompany this specification. v

The invention relates to blades for hair clipping devices, preferablypower driven, and as employed by barbers and others; and refersparticularly to novel features further explained.

In the drawings, Fig. 1 is a side view of the clipper head with myimprovedblades in combination therewith. Fig. 2 is an enlarged detailplan view of the top of the upper blade seen in Fig. 1. Fig. 3 is a planview showing the bottom of the lower blade seen in Fig. 1. Fig. 4 is aplan view of the top of the lower blade, seen in Fig. 3. Fig. 5 is asectional view as taken along the line V-V, Fig. l.

Similar numerals of reference indicate corresponding parts throughoutall the figures of the drawings.

Referring to the drawings, 6 is the upper blade, slidably supported andoperable in the customary manner upon a lower blade 7 in the hairclipping device seen in Fig. 1-. The teeth 8 of the blade 6 are madelonger than in ordinary practice for upper clipper blade constructionand have corrugated or bearded edges 9, 9 for a portion of the distanceinwardly whence the adjacent edges of adjacent teeth terminate in atapering groove asseen in Fig. 2. The teeth 10 of the lower blade 7 maybe fabricated as illus trated in Fig. 4: conforming to the type ofblades as usually employed, or they may also be corrugated or bearded ina manner similar to the edges 9 depending upon the desires of themanufacturer thereof.

In Fig 5, the base of the lower blade 7 is The blade 7 is hollowed outat 13 to secure IR-CLJIPPER BLADE.

ranged within the transverse slots 15. 15 of the upper blade 6 in theassembly Fig. 1, thereby furnishing a guide for the upper blade 6 as itslides on the lower blade 7 in operative practice.

Screw holes 16, 16 through the blade 7 enable the said blade to besecured by screws to the head of the clipper.

Corrugating or bearding the teeth as at 9 produces teeth that are to aconsiderable extent self sharpening under hair cutting operations. andowing to the length of the teeth and to the corrugations, a blade isproduced that can be run at a high rate of speed in a power drivenmachine without choking. thereby producing a clipper that will work at amuch faster speed than is possible with hair clippers ordinarilyemployed.

The curved contour of the lower blade enables the barber to rock thedevice to conform to the curve of the head during hair cuttingoperations and to also cut higher on the head than is customary with theordinary flat bottomed hair clipper. By this rock-able movement, thebarber can do a much smoother job of blending the shorter clipped hairinto the longer or shingled hair without going over the work severaltimes.

Such modifications may be employed as lie within the scope of theappended claim. Having fully described my invention what I now claim asnew and desire to secure by Letters Patent is:

In combination in a. hair cutting device, a lower blade having beardedcutting teeth and an upper blade slidably mounted and controlledthereupon; said lower blade having its base portion convexly curved intwo directions, namely from front to back and from side to side; theupper portion of said bladehaving acentral recess therein extendingtowards the convexly curved base and posts rigid with said baseextending through said recessed portion towards the upper blade element.
